Abstract
(1) Background: Sanghuangporus baumii, a valuable medicinal fungus, has limited studies on its gene function due to the lack of a genetic transformation system. (2) Methods: This study aimed to establish an efficient Agrobacterium tumefaciens-mediated transformation (ATMT) system for S. baumii. This study involved cloning the promoter (glyceraldehyde-3-phosphate dehydrogenase, gpd) of S. baumii, reconstructing the transformation vector, optimizing the treatment of receptor tissues, and inventing a new method for screening positive transformants. (3) Results: The established ATMT system involved replacing the CaMV35S promoter of pCAMBIA-1301 with the gpd promoter of S. baumii to construct the pCAMBIA-SH-gpd transformation vector. The vectors were then transferred to A. tumefaciens (EHA105) for infection. This study found that the transformation efficiency was higher in the infection using pCAMBIA-SH-gpd vectors than using pCAMBIA-1301 vectors. The mycelia of S. baumii were homogenized for 20 s and collected as the genetic transformation receptor. After 20 min of co-culture and 48 h of incubation in 15 mL PDL medium at 25 °C, new colonies grew. (4) Conclusions: These colonies were transferred to PDA medium (hygromycin 4 μg/mL, cefotaxime 300 μg/mL), and the transformation efficiency was determined to be 33.7% using PCR.

Abstract
Sanghuangporus, a medicinal mushroom, has gained significant attention due to its beneficial properties. Phenolic acids are among the major bioactive compounds in Sanghuangporus, known for their antioxidant and anti-inflammatory activities. To precisely quantify the phenolic acid content, we developed a method utilizing ultra-high-performance liquid chromatography with triple quadrupole (UHPLC-QqQ). This study optimized the UHPLC-QqQ conditions to simultaneously separate and detect eight phenolic acids in Sanghuangporus baumii (Pilát) L.W. Zhou and Y.C. Dai, including chlorogenic acid, p-coumaric acid, caffeic acid, cryptochlorogenic acid, protocatechuic acid, ferulic acid, sinapic acid, and syringic acid. The separation process utilized a ZORBAX Eclipse Plus C18 column using 0.01% formic acid and 2 mmol/L ammonium formate in water as the aqueous phase and methanol containing 0.01% formic acid and 2 mmol/L ammonium formate as the organic phase. Calibration curves were constructed using standard solutions to quantitatively determine the phenolic acid content. The results showed significant variation in phenolic acid content among S. baumii fruiting bodies, with Protocatechuic acid, p-coumaric acid, and caffeic acid being the most abundant. This method is valuable for quantifying phenolic acid compounds under different cultivation conditions. It provides excellent sensitivity, selectivity, and reproducibility for the quantification of phenolic acids in Sanghuangporus, contributing to a better understanding of its chemical composition and potential health benefits. This approach represents a novel technical means for the simultaneous analysis of compound phenolic acids in Sanghuangporus fruiting bodies.

Abstract
To further explore the molecular mechanism of triterpenoid biosynthesis and acquire high-value strain of Sanghuangporus baumii, the Agrobacterium tumefaciens-mediated transformation (ATMT) system was studied. The key triterpenoid biosynthesis-associated gene isopentenyl diphosphate isomerase (IDI) was transformed into S. baumii by ATMT system. Then, the qRT-PCR technique was used to analyze gene transcript level, and the widely targeted metabolomics was used to investigate individual triterpenoid content. Total triterpenoid content and anti-oxidant activity were determined by spectrophotometer. In this study, we for the first time established an efficient ATMT system and transferred the IDI gene into S. baumii. Relative to the wild-type (WT) strain, the IDI-transformant (IT) strain showed significantly higher transcript levels of IDI and total triterpenoid content. We then investigated individual triterpenoids in S. baumii, which led to the identification of 10 distinct triterpenoids. The contents of individual triterpenoids produced by the IT2 strain were 1.76-10.03 times higher than those produced by the WT strain. The triterpenoid production showed a significant positive correlation with the IDI gene expression. Besides, IT2 strain showed better anti-oxidant activity. The findings provide valuable information about the biosynthetic pathway of triterpenoids and provide a strategy for cultivating high-value S. baumii strains.

Abstract
BACKGROUND Sanghuangporus baumii is a traditional Chinese medicine with anti-cancer, anti-tumor, and anti-inflammatory effects. Triterpenoids are one of the main medicinal ingredients found in S. baumii. However, the dynamic changes of triterpenoids content and its molecular regulation mechanism are still unclear. OBJECTIVE Some studies have shown that Lanosterol synthase (LS) is a key enzyme involved in the mevalonate pathway (MVA pathway) to produce lanosterol, which is a precursor for synthesizing S. baumii triterpenoids. Therefore, the study of LS gene and expression characteristics can provide clues for the further study of triterpenoids synthesis. METHODS The PCR, RACE PCR, RT-PCR, seamless cloning and prokaryotic expression technology were used to research the gene characteristic and dynamic changes of LS transcription level. RESULTS The S. baumii LS sequence included a 5'-untranslated region (129 bp), a 3'-untranslated region (87 bp), and an open reading frame (2,229 bp) encoding 734 amino acids. The S. baumii LS protein was expressed in E. coli BL21 (DE3). The transcription start site of the S. baumii LS promoter sequence ranged from 1 740 bp to 1790 bp. The LS promoter contained 12 CAAT-boxes, 5 ABREs, 6 G-Boxes, 6 CGTCA-motifs, and so on. The LS transcription levels were the highest on day 11 in mycelia (1.6-fold), and the triterpenoids content also gradually increased. The transcription levels began to decrease on day 13, but the triterpenoids content still increased. CONCLUSION The S. baumii LS was cloned and characterized to help to understand the mechanism of triterpenoids synthesis. In addition, we studied the relationship between LS transcription level and triterpenoid dynamic accumulation, and we found that they had a certain correlation.

Abstract
Sanghuangporus baumii, is a widely used medicinal fungus. The polyphenols extracted from this fungus exert antioxidant, anti-inflammatory, and hypoglycemic effects. In this study, polyphenols from the fruiting bodies of S. baumii were obtained using the deep eutectic solvent (DES) extraction method. The factors affecting the extraction yield were investigated at different conditions. Based on the results from single-factor experiments, response surface methodology was used to optimize the extraction conditions. The scavenging ability of the polyphenols on •OH, DPPH, and ABTS+ was determined. The results showed that the DES system composed of choline chloride and malic acid had the best extraction yield (6.37 mg/g). The optimal extraction parameters for response surface methodology were as follows: 42 min, 58 ℃, 1:34 solid-liquid (mg/mL), and water content of 39%. Under these conditions, the yield of polyphenols was the highest (12.58 mg/g). At 0.30 mg/mL, the scavenging ability of the polyphenols on •OH, DPPH, and ABTS+ was 95.71%, 91.08%, and 85.52%, respectively. Thus, the method using DES was more effective than the conventional method of extracting phenolic compounds from the fruiting bodies of S. baumii. Moreover, the extracted polyphenols exhibited potent antioxidant activity.

Abstract
A farnesyl diphosphate synthase (FPS) cDNA and promoter region was cloned from Sanghuangporus baumii. The gene contains a 150-bp 5'-untranslated region (UTR), a 154-bp 3'-UTR, and a 1062-bp open reading frame (ORF) encoding a 354 amino acid polypeptide. The FPS-DNA includes three exons (nucleotides 1 -123, 184-321, and 505-1305) and two introns (nucleotides 124-183 and 322-504). The FPS protein has a molecular weight of 40.73 kDa, it is hydrophilic with a theoretical isoelectric point of 5.13, and the secondary and three-dimensional structure were analysed. There is a transcription start site at nucleotides 1318-1368 of the promoter, which includes typical eukaryotic promoter elements (TATA Box, CAAT Box, ARBE, AT-rich element, G-box, MBS, Sp1, LTR). FPS was expressed in Escherichia coli BL21, and the recombinant protein (63.41 kDa) was subjected to dodecyl sulphate, sodium salt-polyacrylamide gel electrophoresis (SDS-PAGE). FPS transcription was measured during different developmental stages, and expression in 11 and 13 days mycelia was upregulated 49.3-fold and 125.4-fold, respectively, compared with 9 days mycelia controls. Through analysing, S. baumii triterpenoid content was correlated with the transcription level of FPS during different development stages, and the triterpenoid content peaked at day 15 (7.21 mg/g).
